Помогите решить срочно
1) (x^3-4)'=3x^2 2) (1/x + 2x)'= -1/x^2 + 2 3) (5x^5- )' 25x^4 - 1/2* 4) (1/2 * x^2 + 4 - 2/x)' = x + 2/ + 2/x^2 5) ((3x+7)(7x^3+5x-4))'=3(7x^3+5x-4)+(21x^2+5)(3x+7)=21x^3+15x-12+63x^3+147x^2+15x+35= 84x^3+147x^2+30x+47 6) = 1) (x^5+1)'=5x^4 2) (-1/x - 3x)'= 1/x^2-3 3) (4x^4 + )= 16x^3 + 1/2* 4) (1/3 * x^3 - 2* +5/x)'=x^2 - 1/ - 5/x^2 5) ((5x-4)(2x^4-7x+1))'=5(2x^4-7x+1)+(8x^3-7)(5x-4)=10x^4-35x+5+40x^4-32x^3-35x+28=50x^4-32x^3-70x+33 6)
